Basic check overload is compatible with define during loading

[stepancheg]

define foo(a);
overload foo(a, b) = 1;

is error now even if foo is not called.

Thanks. Looks good now.

I'll look into it tonight.

I think @agemogolk is running tests against an out-of-date compiler.

Yep, build dir mix up. Scratch those test failures.
